Overview

Diagnostic Study of Choice

Gold standard/Study of choice:

  • Transabdominal ultrasonography is the gold standard for the diagnosis of gallstones.[1]
  • The following result of transabdominal ultrasonography is confirmatory of acute cholecystitis:
    • Thickened gallbladder
    • Gallstones
  • The ultrasound should be performed when:
    • The patient presented with right upper quadrant pain, abdominal guarding, fever, and a positive Murphy's sign.
Sequence of Diagnostic Studies

The transabdominal ultrasonography should be performed when:

  • The presented with right upper quadrant pain, abdominal guarding, fever, and a positive Murphy's sign.
  • A positive transabdominal ultrasonography is detected in the patient, to confirm the diagnosis.

Diagnostic Criteria

  • Here you should describe the details of the diagnostic criteria.
  • Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for the diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
  • Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
  • Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
  • Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.
  • To view an example (endocarditis diagnostic criteria), click here
  • If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
  • You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
  • [Disease name] is mainly diagnosed based on clinical presentation. There are no established criteria for the diagnosis of [disease name].
  • There is no single diagnostic study of choice for [disease name], though [disease name] may be diagnosed based on [name of criteria] established by [...].
  • The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
  • The diagnosis of [disease name] is based on the [criteria name] criteria, which includes [criterion 1], [criterion 2], and [criterion 3].
  • [Disease name] may be diagnosed at any time if one or more of the following criteria are met:
    • Criteria 1
    • Criteria 2
    • Criteria 3

IF there are clear, established diagnostic criteria:

  • The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met: [criterion 1], [criterion 2], [criterion 3], and [criterion 4].
  • The diagnosis of [disease name] is based on the [criteria name] criteria, which include [criterion 1], [criterion 2], and [criterion 3].
  • The diagnosis of [disease name] is based on the [definition name] definition, which includes [criterion 1], [criterion 2], and [criterion 3].

IF there are no established diagnostic criteria: 

  • There are no established criteria for the diagnosis of [disease name].
